Contributions to the Neoproterozoic Geobiology
Contributions to the Neoproterozoic Geobiology Bing Shen Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Department of Geosciences Shuhai Xiao (Chair) Robert Bodnar Michal Kowalewski J. Fred Read November 29, 2007 Blacksburg, Virginia Key words: Neoproterozoic, Ediacaran, Ediacara fossils, China, Disparity, Sulfur isotope, Carbon isotope Copyright 2007, Bing Shen Contributions to the Neoproterozoic Geobiology Bing Shen Abstract This thesis makes several contributions to improve our understanding of the Neoproterozoic Paleobiology. In chapter 1, a comprehensive quantitative analysis of the Ediacara fossils indicates that the oldest Ediacara assemblage—the Avalon assemblage— already encompassed the full range of Ediacara morphospace. A comparable morphospace range was occupied by the subsequent White Sea and Nama assemblages, although it was populated differently. In contrast, taxonomic richness increased in the White Sea assemblage and declined in the Nama assemblage. The Avalon morphospace expansion mirrors the Cambrian explosion, and both may reflect similar underlying mechanisms. Chapter 2 describes problematic macrofossils collected from the Neoproterozoic slate of the upper Zhengmuguan Formation in North China and sandstone of the Zhoujieshan Formation in Chaidam. Some of these fossils were previously interpreted as animal traces. Our study of these fossils recognizes four genera and five species. None of these taxa can be interpreted as animal traces. Instead, they are problematic body fossils of unresolved phylogenetic affinities. Chapter 3 reports stable isotopes of the Zhamoketi cap dolostone atop the Tereeken diamictite in the Quruqtagh area, eastern Chinese Tianshan. Our new data indicate that carbonate associated sulfate (CAS) abundance decreases rapidly in the basal 34 cap dolostone and δ SCAS composition varies between +9‰ and +15‰ in the lower 2.5 34 m. -

Traces of Locomotion of Ediacaran Macroorganisms
geosciences Article Traces of Locomotion of Ediacaran Macroorganisms Andrey Ivantsov 1,* , Aleksey Nagovitsyn 2 and Maria Zakrevskaya 1 1 Laboratory of the Precambrian Organisms, Borissiak Paleontological Institute, Russian Academy of Sciences, Moscow 117997, Russia; [email protected] 2 Arkhangelsk Regional Lore Museum, Arkhangelsk 163000, Russia; [email protected] * Correspondence: [email protected] Received: 21 August 2019; Accepted: 4 September 2019; Published: 11 September 2019 Abstract: We describe traces of macroorganisms in association with the body imprints of trace-producers from Ediacaran (Vendian) deposits of the southeastern White Sea region. They are interpreted as traces of locomotion and are not directly related to a food gathering. The complex remains belong to three species: Kimberella quadrata, Dickinsonia cf. menneri, and Tribrachidium heraldicum. They were found in three different burials. The traces have the form of narrow ridges or wide bands (grooves and linear depressions on natural imprints). In elongated Kimberella and Dickinsonia, the traces are stretched parallel to the longitudinal axis of the body and extend from its posterior end. In the case of the isometric Tribrachidium, the trace is directed away from the margin of the shield. A short length of the traces indicates that they were left by the organisms that were covered with the sediment just before their death. The traces overlaid the microbial mat with no clear signs of deformation under or around the traces. A trace substance, apparently, differed from the material of the bearing layers (i.e., a fine-grained sandstone or siltstone) and was not preserved on the imprints. This suggests that the traces were made with organic material, probably mucus, which was secreted by animals in a stressful situation. -
